Boeing made some unnecessary and troublesome deviations from the classic 737 when they rolled out the -700, the first NG, in 1997. One was the mechanism of the landing gear handle you see in the video. The handle operates a cable run that goes back to a shaft that operates the landing gear hydraulic control valve in the wheel well. It was trouble free on the classics. On the NG, Boeing wanted to move the forward cable pulley away from the handle, I suppose to make more room for the new instrument panels. So they inserted a push-pull Teleflex cable between the handle and the pulley. Every mechanic in aviation knows how troublesome such cables can be, no matter what kind of airplane they are used in. Sure enough, after a few years of service the push-pull cables began binding in the sheaths, and a -700 crew found that they could not lower the handle to put the gear down for landing. They tried so hard that they actually bent the gear handle. Finally they were able to free fall the gear into position by the trusty handles and cables shown in the video, and land the plane safely. Boeing did a lot of other stupid stuff that made me wonder if the designers of the NG were even familiar enough with the classics to know what works and what does not work on a 737. Maybe I should write a book.

Them planes are alot bigger then people think they are. Interesting

The Max 10 gears are actually longer but are still stored in the same size bay. The gears are telescopic so as they are retracted the length is shorted.

I was in charge of landing gear maintenance for a commercial jet liner once. We had one plane that never retracted the front gear. It was always in the down position. Never did figure that one out but its doesn't really matter because no one really sees it at 30, 000 feet.

Are the wheel cavities heated to prevent those tubing and fluid in them from freezing at high altitudes?

[Pilot_Alex_Sax]

Why in the up position there is a sort of swing before the complete closure?

[idolhanz]

Amazing design with no outer followup main landing gear door ro cover that exposed tire...not necessary, saves weight..

[JoshRendall]

How come the wheels are still visible even after they retract?

[rmshivo]

That musta been a hard landing on the left boggie

[patthewoodboy]

the problem of the 737 is right here, no room for an extended undercarriage, therefore no room for big engines

[balazsegressy]

Who ever engineer did the operational test failed to read the AMM. The throttle levers shoud be advanced forward to extinguish the red lights once the gear is up. When the throttle is not advanced the landing configuration warning is active and keeping the red lights on. So the complete operational test is incorrect because the indication system correct operation could not be verified.

To much shit can go wrong they say it's safer to fly than drive

if it's a boeing...I ain't going!!
